Description

  The present invention relates to a lock mode in which a content discharge operation is blocked by a sliding operation of a push-down rotation type content discharge operation unit, and a lock release mode in which the content discharge operation can be performed by canceling this blocked state. The present invention relates to a content discharge operation locking mechanism. For aerosol type products and pump type products.

  In particular, guide portions (first and second guide portions) are formed on a cover cap that guides the sliding movement of the operation portion, and first and second guided portions corresponding to the guide portions are formed on the operation portion. The present invention relates to a formed content discharge operation locking mechanism.

  In the lock mode, both the first and second guided portions are guided and held in the guide portion, and in the unlock mode after sliding from there, the guide holding state of the guide portion and the second guided portion until then is maintained. As a result, the operation portion rotates around the first guided portion.

  In addition, during the contents release operation in the unlock mode, the entire operation portion, that is, the entire portion including the guided portion to the cover cap at the time of the sliding operation is not deformed and remains in the original operation portion shape. It is designed to rotate.

  In addition, a shutter unit is provided that hinges with the top plate-like part of the operation unit and shuts off the contents discharge port from the external space area in the lock mode, and the shutter unit is moved by a slide operation of the operation unit. Thus, the shutoff state of the discharge port is released.

  In this specification, the state in which the valve member such as the stem is closed and the content is not released to the external space area is called a stationary mode as necessary, and the valve member is opened by the pressing operation of the operation unit, and the content is The content injection state discharged to the external space area is called an operation mode.

  The term “hinge coupling” is used to indicate a coupling mode in which the first component is pivotally integrated with the second component.

  Further, the term “opening” is used to include not only a through-hole and a hole, but also a “concave portion not penetrating”, which leads from one side to the back side.

  Also, the outlet side of the contents to the external space area is described as “front”, and the opposite side as “rear”. The left side of FIGS. 1 to 4 and 7 to 9 is “front” and the right side is “rear”.

  In addition, the directions substantially orthogonal to the front-rear direction in the horizontal plane, for example, the vertical direction in FIGS.

  Conventionally, in an aerosol-type product, a content discharge operation lock mechanism that selectively sets a lock mode for preventing a content discharge operation and a lock release mode for enabling a content discharge operation by a slide operation of a content discharge operation unit. Has been proposed (see Patent Document 1).

  In the case of this content discharge operation locking mechanism, it is generally assumed that the operation unit is a vertically moving type operation unit without rotation, and the operation unit moves in the front-rear direction while being guided by the nozzle unit (discharge passage unit). And unlock mode are selectively set.

  In the lock mode for preventing the content discharge operation, the lock piece formed on the operation portion is set in a state of being substantially in contact with the upper surface of the housing (cover cap).

  Therefore, even if the user tries to push down the operation unit in the lock mode, the operation unit cannot be moved downward while a part of the lock pieces is held on the upper surface of the housing. That is, the content discharge operation in the downward direction of the operation unit is prevented.

The basic features of the content discharge operation locking mechanism in the non-shutoff mode of FIGS.
(31) In the lock mode of Fig. 1,
The columnar convex portion 1g of the operation portion 1 is held at the front end portion of the linear front opening 2k in a state of being placed on the upper wide portion 2e of the cover cap 2,
The prismatic convex portion 1j (front side prismatic convex portion 1k + rear side prismatic convex portion 1p) of the operation unit 1 is held by the linear rear opening 2n in a state of being placed on the upper narrow portion 2g of the cover cap 2. ,
(32) When the unlocking mode of FIG. 2, that is, when the operation unit 1 at the position of FIG.
The columnar convex portion 1g of the operation portion 1 is held by the arc-shaped portion 2m at the rear end portion of the linear front opening 2k while being placed on the upper wide portion 2e of the cover cap 2.
The prismatic convex portion 1j (front side prismatic convex portion 1k + rear side prismatic convex portion 1p) of the operation unit 1 is shifted from the upper narrow portion 2g of the cover cap 2 and shifted rearward thereof, that is, the prismatic convex portion. 1j, the upper narrow portion 2g and the linear rear opening 2n are released from the vertical engagement state,
-A part of the parallel surface 1q of the rear prismatic convex portion 1p is set so as to be substantially in contact with the inner surface side of the cylindrical upright portion 2a so that the operation portion 1 does not slightly rotate in the horizontal plane,
(33) In the content injection state of FIG. 3, that is, in the operation mode in which the top plate portion 1a of the operation unit 1 of FIG.
The operation unit 1 rotates in the clockwise direction in the figure around the columnar convex portion 1g held by the arc-shaped portion 2m of the cover cap 2 without causing any special deformation,
-With this rotation, the lower end surface of the inner rear hanging portion 1f of the operation portion 1 pushes down the bottom surface portion of the driven concave portion 3d of the discharge passage portion 3,
-With this depression, the discharge passage portion 3 and the stem 4 attached to the fitting portion 3b thereof are interlocked downward while tilting clockwise in the figure.
And so on.

  Here, the discharge passage portion 3 in the operation mode is tilted by the displacement of the connecting portion 3e with the cover cap 2.

  Moreover, the known valve action part shifts from the closed state so far to the open state by the downward movement of the stem 4 against the upward elastic force of the known coil spring.

  By the opening state shift of the valve action portion, the contents of the container main body 5 are roughly transferred from the discharge port 3a to the external space via the "container main body 5-open valve action portion-the internal passage of the stem 4-content passage 3c". Is injected into the area.

  When the operation unit 1 is slid backward from the lock mode of FIG. 1 to the lock release mode of FIG. 2, the cylindrical convex portion 1 g of the operation unit is the front curved surface of the cover cap 2 at the initial stage. Get over the convex part 2f. The user gets a sense of click when getting over this.

  In addition, the portion of the linear front opening 2k immediately before the cylindrical convex portion 1g enters the arc-shaped portion 2m at the final stage of the backward sliding operation to the unlocking mode is narrowed down in the vertical direction. Therefore, the user can also obtain a click feeling corresponding to the end of the slide operation for releasing the lock mode when the cylindrical convex portion 1g passes through the narrowed portion.

  The columnar convex portion 1g in the unlocking mode of FIG. 2 is held in a form that can be rotated by an arc-shaped portion 2m formed immediately after the above-described narrowed portion. That is, the cylindrical convex portion 1g can act smoothly as the rotation center of the operation portion 1 as described above.

  The content injection state of FIG. 3 stops when the user stops the content discharge operation of the operation unit 1, that is, releases the operation of pushing the operation unit in the clockwise direction in the drawing.

  When the user stops the pressing operation, the stem 4 and the discharge passage portion 3 integrated with the stem 4 are driven upward by the elastic force of a known coil spring.

  With the upward movement of the discharge passage portion 3 and the stem 4, the connecting portion 3e with the cover cap 2 returns to the initial state, and the discharge passage portion is shifted to the position of the unlocking mode in FIG.

  However, even after this shift, the inner posterior lower portion 1 f of the operation portion 1 remains in contact with the bottom surface portion of the driven concave portion 3 d of the discharge passage portion 3. That is, the prismatic convex portion 1j of the operation portion 1 is positioned lower than that in FIG. 2 by the vertical direction up to the contact state of the inner trailing portion 1f.

When returning to the lock mode of FIG. 1 after releasing the pressing operation described above, when the prismatic convex portion 1j is slid in the forward direction on the left side of the drawing from the lower position where it abuts the driven concave portion 3d,
The operation unit 1
(41) First, the columnar convex portion 1g passes through the narrowed portion immediately before the arc-shaped portion 2m, and the front prismatic convex portion 1k is guided by the tapered surface 1m so that the upper width of the cover cap 2 is increased. Ride on the rear end portion of the narrow portion 2g, that is, turn slightly counterclockwise in the figure around the cylindrical convex portion 1g,
(42) Thereafter, the cylindrical convex portion 1g is guided by the upper wide portion 2e and the linear front opening 2k of the cover cap 2, and the bottom surface portion such as the front prismatic convex portion 1k is the rear curved convex portion. In 2h, it ’s a little lifted,
(43) Further, the columnar convex portion 1g moves over the front curved surface convex portion 2f to the front end portion of the linear front opening portion 2k, and the prismatic convex portion 1j is entirely linear rear opening portion. It moves into 2n and moves to a state in which its front prismatic convex portion 1k is in contact with the upper narrow portion 2g.

  When the slide operation to return to the lock mode is performed, the user moves the columnar convex portion 1g at the initial stage of operation through the narrowed portion immediately before the arc-shaped portion 2m and the columnar convex portion 1g at the final stage of the operation. When getting over the front curved convex portion 2f, a click feeling is obtained.

To incorporate the operation unit 1 into the cover cap 2,
(51) Set the operation unit directly above the cover cap in the longitudinal relationship of FIG.
(52) Next, the operation unit is fitted downward with respect to the cover cap, and once set to the unlock mode position,
(53) Next, the operation unit may be slid forward to set the lock mode position in FIG.
